MicroFiler is an ICAEW regulated chartered accountants firm specialising in annual accounts, corporation tax, confirmation statements, and tax returns for micro companies. The firm is run by ICAEW Chartered Accountants with more than 20 years of experience in practice. Alongside the core micro-company work, the firm also files for dormant limited companies, small limited companies, sole traders, and individual landlords. Every service runs on a fixed annual or monthly fee, with all prices published openly on the website.
MicroFiler is built exclusively for UK micro-entity limited companies, businesses that meet at least two of the following criteria in a financial year:
This segment has specific filing requirements under FRS 105, and that's exactly where we focus.
FRS 105 makes the work predictable in shape, which means consistent pricing, fast turnaround, and reliable quality across every client. Over time, we've built deep familiarity with the scenarios that come up year after year: first-year accounts, dormant-to-active transitions, single-director salary and dividend structures, and IR35 boundary cases.
Most of our clients are directors running their own business without an in-house finance function. We handle the filing end-to-end, directly with HMRC and Companies House, and only surface the decisions that actually need their input.
Three principles guide how the firm operates.
Every service has a fixed price listed on the website. Dormant company accounts and corporation tax cost £285 a year. Micro company accounts and corporation tax cost £445 a year. Small company accounts and corporation tax cost £695 a year. MTD for Income Tax costs £199 setup plus from £25 a month. Self Assessment returns cost a fixed fee per return.
The fixed price covers the full filing service, including bookkeeping review, draft preparation, client review, and final submission. In practice, fixed pricing means clients know the cost before they engage, not after the work has been done.
MicroFiler is registered with HMRC as an authorised tax agent and submits filings directly to HMRC and Companies House on behalf of clients. Clients do not need their own Government Gateway accounts, presenter codes, or Companies House WebFiling credentials for routine filings. Where HMRC or Companies House query a submission, the firm responds to and resolves the query as the registered agent.
Four client groups make up most of the firm’s work.
Active limited companies that meet at least two of HMRC’s micro-entity criteria: turnover up to £1,000,000, balance sheet up to £500,000, or 10 or fewer employees. The firm files statutory accounts under FRS 105, the CT600 corporation tax return, and the annual confirmation statement.
Limited companies that need to remain on the Companies House register without active trading. The firm files dormant accounts (form AA02), the corporation tax return where required, and the annual confirmation statement.
Active limited companies that meet at least two of the small company criteria: turnover up to £15,000,000, balance sheet up to £7,500,000, or 50 or fewer employees. The firm files statutory accounts under FRS 102 Section 1A, the CT600 corporation tax return, and the annual confirmation statement.
Self-employed sole traders and individual UK landlords filing Self Assessment returns or, from April 2026 onward, MTD for Income Tax quarterly updates and final declarations. Common income types covered include trading profit, rental income from one or multiple properties, dividends, savings interest, and capital gains.
Four points define the firm’s positioning.
Years of repeating the same statutory filings produce a level of speed and accuracy that mixed-practice firms find harder to maintain across more varied work. The depth shows up in turnaround times, low error rates, and the quality of the questions the firm asks during preparation.
Fixed fees of £285 a year for dormant companies, £445 a year for micro companies (with turnover up to £40,000 and total assets up to £90,000), and £695 a year for micro or small companies (with total turnover up to £90,000 and total assets up to £200,000). This pricing sit below the rates many firms charge for the same statutory work. The price point reflects how the service is built and run rather than a discount on expertise.
MicroFiler is led by an ICAEW Chartered Accountant with over 20 years of experience filing accounts and tax returns for UK companies. That continuity of experience matters when filing rules change, as they have repeatedly across that period: the introduction of FRS 105 in 2016, MTD for VAT in 2019, the Economic Crime and Corporate Transparency Act in 2023, and MTD for Income Tax in 2026.
MicroFiler operates under the registrations required of UK accounting firms.
The firm is registered with HMRC as an authorised tax agent for corporation tax, Self Assessment, and MTD for Income Tax filings. The agent registration permits the firm to submit returns directly to HMRC on behalf of clients and to handle HMRC correspondence as the registered agent.
The firm is registered with the Information Commissioner’s Office (ICO) for the processing of personal data under UK GDPR.
